Thank you for viewing this dress. This is a knee-length dress. I would like to pass this on to someone who will use it. It is new, without tags. The size is 38, which I believe is equivalent to a size M. It has lining on both the top and bottom, so I don't think it's see-through. Please understand that it has been stored at home. I'm hesitant to sell it at the moment, so please refrain from price negotiations. Dry cleaned. If you have any questions, please feel free to comment.
